The same idea is not the same post
A truncated hook loses the point
Cutting a LinkedIn post at 280 characters rarely produces a complete X post. The short version needs a new opening and a deliberate ending.
Media assumptions change
Instagram publishing requires an image in the current Blastopus connector. A text-only version that works on LinkedIn cannot simply be sent unchanged.
Calls to action are contextual
A discussion prompt, a product announcement, and a link click are different jobs. Each network version should have one clear job.
Network culture matters
Spacing, hashtags, link placement, formality, and how much background a reader expects vary. Mechanical duplication makes the post feel imported.
Platform limits and adaptation jobs
These are the working character caps enforced by Blastopus today. Networks may apply additional rules by post type, account, media format, or API version, so treat validation as a final check—not permission to fill every character.
| Network | Working cap | Adaptation job | Blastopus status |
|---|---|---|---|
| X | 280 | One sharp point, useful context, and a clean opening line. | Live |
| 3,000 | Professional context, readable spacing, and a developed takeaway. | Live | |
| 63,206 | Conversational context and a clear reason for the reader to respond. | Preview | |
| 2,200 | Caption structured around the visual; publishing requires an image. | Preview | |
| TikTok | 2,200 | A caption that supports the video rather than pretending to be the video. | Preview |
| YouTube | 5,000 | Description or community-post copy with enough context to stand alone. | Preview |
| Threads | 500 | Direct, conversational writing with room for a useful observation. | Preview |
| 500 | Search-friendly description tied to the destination or visual asset. | Preview | |
| Bluesky | 300 | Compact, human copy without carrying over every campaign element. | Live |
| Mastodon | 500 | Self-contained context suited to the norms of the chosen instance. | Live |
One source, five deliberate steps
Choose one source of truth
Start from a useful idea, article, transcript, product launch, or goal. Preserve the facts and intended outcome before changing format.
Define what each network should do
Decide whether each version should teach, invite discussion, announce, summarize, or send qualified readers somewhere useful.
Adapt instead of truncating
Rewrite the hook, structure, length, call to action, and media assumptions for each destination. Do not merely cut the same paragraph at different character counts.
Review the variants together
Check factual consistency, banned words, links, handles, image requirements, and tone before approving the set.
Schedule and verify
Publish through live connectors, keep preview networks clearly simulated, and review failures from one queue rather than assuming every API accepted the post.
Use Mimic when content already exists
Paste an article URL, YouTube URL, or raw text. Mimic extracts the source, finds distinct angles, adapts every angle for the selected channels, and puts the week into pending approval.
Use Autopilot when you have a goal
Give Autopilot an outcome and cadence. It creates a seven-day plan, adapts each idea for the chosen channels, and waits for approval rather than publishing behind your back.
A final operational check
Cross-posting is complete only after verification. Check the queue for platform errors, confirm the live URL where available, and keep preview-mode results separate from posts that actually reached a network.
